Cook not worried, but knows he needs improvement

TUCSON — Aaron Cook’s side sessions have been great. His game performances? Not so much. He has allowed 15 runs over his last 5 2/3 innings, creating some slight hand-wringing in the Rocky Mountain region.

What gives? In the last two games, he has not maintained a consistent release point, causing his sinker to remain elevated, particularly on the inner-half of the plate.

“I have three more starts and I might even ask some hitters to step in against me (during a live BP) if I need extra work,’’ Cook said. “There’s plenty of time left.’’

Added manager Jim Tracy, “He’s not right. He’s been inconsistent. But from my experience, it often takes finesse pitchers longer than power pitchers.’’

Tracy cited Jeff Weaver And Omar Daal as examples of pitchers he’s had that struggled mightlly in spring then had no issues once the bell rang on opening day.

But I do know this, the Rockies would like some results to hold onto during at least two of Cook’s next three starts.
